Title: Novel glycol-based complex including sodium hydroxide and production thereof
Inventor: FUKUMA YASUNOSHIN
IPC: C07C31/20
Filed: 1985-12-04
Abstract: NEW MATERIAL:A glycol-based complex including sodium hydroxide and produced by including sodium hydroxide and water in glycol. EXAMPLE:1,6-Hexanediol complex including sodium hydroxide and produced by including sodium hydroxide and water in 1,6-hexanediol. USE:An intermediate for facilitating the production of high-purity sodium hydroxide in a sodium hydroxide industry. PREPARATION:A glycol-based complex including sodium hydroxide can be produced by contacting glycol with an aqueous solution of sodium hydroxide. The formation of the inclusion complex enables selective separation of sodium hydroxide from an aqueous solution of sodium hydroxide produced e.g. by the electrolysis of sodium chloride. Since the complex can be easily decomposed simply by adding water thereto, sodium hydroxide can be purified by an energy- saving process without necessitating the energy for distillation, etc.

Title: Clock skew suppressing circuit
Inventor: HIGAKI NAOSHI
IPC: H03K5/13
Filed: 1993-10-29
Abstract: PURPOSE:To suppress clock skew without enlarging the buffer size by applying a clock signal to one input of a differential amplifier, applying a constant voltage to the other input and applying a signal extracted from the inverted output or non-inverted output of the differential amplifier to an internal circuit. CONSTITUTION:A clock signal CLKLOCAL to be transmitted through a transmission line provided with a buffer or wiring to the internal circuit of a semiconductor chip is applied to one input (+) of a differential amplifier 20. A constant potential VREF is applied to another input (-). Corresponding to this potential, the transition time of a non-inverted output CLKOUT of the differential amplifier 20 is changed. While the potential on the reference side (-) is set at a low level, for example, when the potential on the comparison side (+) is enlarged a little, the output state is immediately transited but while the potential on the reference side (-) is set at a high level, the output state is not transited until the potential on the comparison side (+) is increased to a high level. Therefore, the skew can be suppressed by adjusting the transition time of the output.

Title: Lead smelting method by using electric furnace
Inventor: MOCHIDA HIROMI
IPC: C22B7/02
Filed: 1986-11-17
Abstract: PURPOSE:To smelt lead slag by using an electric furnace at a low cost, by blowing, together with air, a powder mixture prepared by mixing lead slag composed principally of PbSO4, fuel, a solvent, and a reducing agent into a high-temp. melt in the electric furnace at a specific blowing pressure. CONSTITUTION:At the time of smelting lead slag composes principally of PbSO4 by using an electric furnace, the powder mixture previously prepared by mixing lead slag, fuel, a solvent, and a reducing agent is blown into the high-temp. melt in the electric furnace together with air at a gauge pressure of 0.7-5kg/cm<2>. According to the above method, electric power cost can be reduced since air and fuel are burnt in the melt and the greater part of the resulting combustion heat can be utilized, and moreover, throughput can be increased because treatment is speeded up as reaction rapidly proceeds owing to high- speed blowing into the melt.
